How come My numbers and symptoms are worse on a low-carb diet?

A while back, I was diagnosed with reactive hypoglycemia. I recently got an OGTT and fasting was 80, one hour was 133, two hour was 73, three hour was 56, and four hour was 42. My blood sugars also drop if I fast. Additionally, I recently had my fasting insulin tested which was a couple points above normal range (so slightly elevated). My A1C, however, is currently 4.5. It's very confusing to me but anyways...

I tried a low carb diet. I was eating greens/salads, lots of eggs, chicken, fish, cheddar cheese, etc. To my surprise, I began crashing more often, was always tired, always hungry, blurry vision, dizziness, and also rapidly put on 30 pounds. I didn't want to go back to my former eating habits so I did some experimenting. I switched from a low carb, high protein, moderate fat to a moderate carb, moderate fat, low protein diet. Basically, my new diet consists of lots of fruit, veggies, beans, flax, chia seeds, whole/ancient grains, olive oils, nuts, occasional seafood, etc. I cut out dairy and most meats. Despite my increased carb intake and lower protein, I stopped crashing, have more energy, rarely feel hungry, no more dizziness, and am losing the weight I gained from low carb, and my A1C improved. I'm just curious, why is this?

Thank you for your answers and support. I'm not trying to rant by the way. Have just been confused because after lots of research and what I've been told, low-carb is supposed to be helpful for people with metabolic issues (it made my reactive hypoglycemia even worse though). I'm trying my best to prevent my RH from becoming diabetes. Not sure exactly how that works but I've heard that RH often leads to diabetes, plus diabetes runs strongly in my family.

Best thing is you found what works for you, I worked with two ladies that had what you do shocked me to see it then my wife started having the same thing.

My theory as to how reactive hypoglcemia becomes diabetes, carbs trigger insulin but your body is malfunctioning and release too much insulin. Your blood glucose drops too low. Eventually your body, in self protection mode, develops a resistance to insulin. As this resistance builds, your body that is already malfunctioning, continues it's hyper reaction and builds a resistance to insulin that finally outstrips ypur body's ability to produce insulin or your pancreas finally starts getting tired of over producing and reduces insulin production but the insulin resistance does not reduce accordingly. As a result ypur blood glucose numbers gradually begin rising until your diagnosed as type 2 diabetic. In my opinion it is possible hypoglcemia is actually an early stage of diabetes. At least for some of us.
